[0021] See also Figure 1-4 , the utility model provides a technical solution:

[0022] A positioning sheet metal device for processing a display frame comprises a working box 1 and an L-shaped frame 14. A strip opening 1 is provided on the top surface of the working box 1, and a positioning component for positioning the display frame is provided in the strip opening 1. By using the positioning component, the display frame can be fixed in the center, which is beneficial to punching holes in the display frame. Two U-shaped frames 10 can move relative to each other, so that it is convenient to position and fix display frames of different sizes, thereby realizing the practicality of the positioning sheet metal device. A strip opening 2 is provided at the rear end of the top surface of the working box 1, and a driving member for moving the L-shaped frame 14 is provided in the strip opening 2. By using the driving member, it is convenient to move the punching component horizontally, which is beneficial to punching holes in the display frame. A supporting component for lifting the display frame is provided in the working box 1. By using the supporting component, it is convenient to support the display frame, avoid workers holding the display frame, thereby reducing the labor intensity of workers and facilitating the positioning and fixing of the display frame. A punching component for punching holes in the display frame is provided on the L-shaped frame 14, so that it is convenient to punch holes in the display frame.

[0023] The positioning assembly includes a bidirectional screw rod 15 rotatably arranged in the working box 1 and a driving motor 2 arranged at one end of the bidirectional screw rod 15. The outer walls of both ends of the bidirectional screw rod 15 are threadedly connected with threaded sleeves 4, and the top of the threaded sleeve 4 movably passes through the outside of the strip opening and is fixedly connected to a U-shaped frame 10. An electric push rod 11 is arranged on the top of the U-shaped frame 10. The telescopic end of the electric push rod 11 extends into the U-shaped frame 10 and is fixedly connected to a pressure plate 9. The positioning and fixation of the display frame is achieved by the coordinated use of the electric push rod 11 and the pressure plate 9.

[0024] In the utility model, rubber pads 7 are provided on the inner bottom surfaces of the pressing plate 9 and the U-shaped frame 10. The rubber pads 7 play a buffering role to avoid scratches on the display frame between the pressing plate 9 and the U-shaped frame 10, thereby facilitating the protection of the display frame. At the same time, the friction between the pressing plate 9, the U-shaped frame 10 and the display frame is increased, thereby facilitating the stable positioning and fixing of the display frame, which is beneficial to the punching of the display frame.

[0025] In the utility model, the support assembly includes an electric telescopic rod 18 arranged in the working box 1 and a rectangular plate 17 arranged at the telescopic end of the electric telescopic rod 18. Support rods 16 are arranged at the four corners of the top surface of the rectangular plate 17, and the top of the support rod 16 movably passes through the outside of the working box 1 and is fixedly connected to the support plate 6. Through the use of the electric telescopic rod 18, it is convenient to adjust the position of the support plate 6 so that the bottom of the display frame is higher than the bottom of the U-shaped frame 10, thereby facilitating the positioning of the display frame.

[0026] In the utility model, the punching assembly includes a rectangular groove opened on the inner top surface of the L-shaped frame 14, a screw rod 20 rotatably set in the rectangular groove and a servo motor 8 set on the screw rod 20. The outer wall of the screw rod 20 is threadedly connected with a threaded sleeve 3 slidably set in the rectangular groove. A hydraulic cylinder 13 is provided at the bottom of the threaded sleeve 3 to facilitate the up and down movement of the punch 12, thereby realizing punching of the display frame; the punch 12 is installed at the telescopic end of the hydraulic cylinder 13.

[0027] In the utility model, the driving member includes a screw rod 19 rotatably arranged in the second strip opening and a servo motor 3 arranged on the screw rod 19. The outer wall of the screw rod 19 is threadedly connected with a threaded sleeve 5 slidably arranged with the second strip opening. The top of the threaded sleeve 5 is fixedly connected to the L-shaped frame 14.

[0028] Working principle: When the utility model is used, when positioning the outer frame of the display, first open the electric telescopic rod 18, and the telescopic end of the electric telescopic rod 18 is extended to drive the rectangular plate 17 to move upward, thereby driving the support rod 16 to move upward, thereby driving the support plate 6 to move upward, and the support plate 6 is moved to be parallel to the middle of the U-shaped frame 10 through the electric telescopic rod 18; then the outer frame of the display is placed on the support plate 6;

[0029] Then, the driving motor 2 is started, and the bidirectional screw rod 15 is driven to rotate by the output shaft of the driving motor 2, thereby driving the threaded sleeve 4 to move relatively, thereby driving the U-shaped frame 10 to move relatively. With the cooperation of the two U-shaped frames 10, it is convenient to center the display frame to the middle of the working box 1, and then open the electric push rod 11, and drive the pressing plate 9 to move downward by the telescopic end of the electric push rod 11, so as to realize the positioning and fixing of the display frame; when the positioning and fixing of the display frame is completed, the electric telescopic rod 18 is controlled to reset the support plate 6 to prevent the support plate 6 from affecting the punching of the display frame;

[0030] When punching the display frame, the L-shaped frame 14 can be moved back and forth in the horizontal direction by controlling the servo motor 1 3, thereby adjusting the horizontal reciprocating movement of the punch 12, and then the longitudinal position of the punch 12 can be adjusted by the servo motor 2 8; through the above operation, it is convenient to punch holes in the display frame.

[0031] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
